Abstract

An embodiment reinforcement member for a rear floor panel is disposed on an upper surface of the rear floor panel, is coupled to a rear floor center cross member that is configured to support a rear surface of the rear floor panel, and is connected to a maintenance cover hole in the rear floor panel from the rear floor center cross member.

Claims (54)

1 . A reinforcement member for a rear floor panel, the reinforcement member comprising:

a rigidity transfer portion that protrudes, is spaced apart from an upper surface of the rear floor panel, and extends from a rear end to a front end of the reinforcement member,

wherein:

the rigidity transfer portion comprises:

a rear portion extending forward from the rear end of the reinforcement member; and

a front portion extending from the rear portion to the front end of the reinforcement member,

the reinforcement member is configured to:

be disposed on the upper surface of the rear floor panel;

be coupled to a rear floor center cross member that supports a rear surface of the rear floor panel; and

be connected to a maintenance cover hole in the rear floor panel from the rear floor center cross member, and

the front portion is divided into two branches.

2 . The reinforcement member of claim 1 , further comprising:

a front extension extending from the front end to the maintenance cover hole; and

a rear extension extending from the rear end to an end of the rear floor center cross member.

3 . The reinforcement member of claim 1 , wherein a first length direction of the reinforcement member extends in an inclined direction with respect to a second length direction of the rear floor panel.

4 . The reinforcement member of claim 1 , wherein a first width of the rear end of the reinforcement member is greater than a second width of the front end thereof.

5 . A reinforcement member for a rear floor panel, the reinforcement member comprising:

a rigidity transfer portion that protrudes, is spaced apart from an upper surface of the rear floor panel, and extends from a rear end to a front end of the reinforcement member,

wherein:

the rigidity transfer portion comprises:

a rear portion extending forward from the rear end of the reinforcement member; and

a front portion extending from the rear portion to the front end of the reinforcement member,

the reinforcement member is configured to:

be disposed on the upper surface of the rear floor panel;

be coupled to a rear floor center cross member that supports a rear surface of the rear floor panel; and

be connected to a maintenance cover hole in the rear floor panel from the rear floor center cross member, and

the rigidity transfer portion further comprises a pair of legs spaced apart from both side surfaces of the rear portion and connected to both side surfaces of the front portion.

6 . The reinforcement member of claim 5 , further comprising:

a front extension extending from the front end to the maintenance cover hole; and

a rear extension extending from the rear end to an end of the rear floor center cross member.

7 . The reinforcement member of claim 5 , wherein a first length direction of the reinforcement member extends in an inclined direction with respect to a second length direction of the rear floor panel.

8 . The reinforcement member of claim 5 , wherein a first width of the rear end of the reinforcement member is greater than a second width of the front end thereof.

9 . A vehicle comprising:

a vehicle body comprising a rear floor panel;

a maintenance cover hole in the rear floor panel;

a rear floor center cross member coupled to a lower surface of the rear floor panel;

a reinforcement member disposed on an upper surface of the rear floor panel, coupled to an inclined portion of the rear floor panel, coupled to the rear floor center cross member, and connected to the maintenance cover hole from the rear floor center cross member;

a seat disposed over the rear floor panel;

a rigidity transfer portion that is spaced apart from the upper surface of the rear floor panel and extends from a rear end to a front end of the reinforcement member,

wherein:

the rigidity transfer portion comprises:

a rear portion extending forward from the rear end of the reinforcement member; and

a front portion extending from the rear portion to the front end of the reinforcement member, and

the front portion is divided into two branches.

10 . The vehicle of claim 9 , wherein:

the front portion and the rear portion have a step difference with respect to the front portion, and

the inclined portion is inclinedly connected between the front portion and the rear portion.

11 . The vehicle of claim 10 , wherein the reinforcement member is disposed on an upper surface of the inclined portion.

12 . The vehicle of claim 9 , wherein the rigidity transfer portion comprises a pair of legs spaced apart from both side surfaces of the rear portion and connected to both side surfaces of the front portion.

13 . The vehicle of claim 9 , further comprising:

a front extension extending from the front end to the maintenance cover hole; and

a rear extension extending from the rear end to an end of the rear floor center cross member.

14 . The vehicle of claim 9 , wherein a first length direction of the reinforcement member extends in an inclined direction with respect to a second length direction of the rear floor panel.

15 . The vehicle of claim 9 , wherein a first width of the rear end of the reinforcement member is greater than a second width of the front end thereof.
